Call redis.replicate_commands() at the top of every Lua script that
reads redis.call('TIME'), so the resulting writes (ZADD, ZREMRANGEBYSCORE,
SET, DEL, EXPIRE) replicate correctly on Redis 3.2-4.x.
This is a no-op on Redis 5.0+, where effects replication is the default.
The function remains a public API on Redis 7.0+ (deprecated but supported)
and is still the documented way to opt into effects replication on older
versions, so calling it unconditionally is safe and forward-compatible.
Affected scripts (8 in total, all already using redis.call('TIME') by
design to avoid client-side clock skew across multiple app instances):
- concurrency_cache.go: acquireScript, getCountScript,
cleanupExpiredSlotsScript
- session_limit_cache.go: registerSessionScript, refreshSessionScript,
getActiveSessionCountScript, isSessionActiveScript
- user_msg_queue_cache.go: releaseLockScript
Scripts that do not invoke non-deterministic commands are intentionally
left untouched.
